A Century of Farm Household Income Estimation and Comparison

ABSTRACT Understanding farm household (FHH) income has been a central concern of agricultural economists and policymakers for more than a century. This review traces the evolution of concepts, definitions, data sources, analytical approaches and empirical evidence used to estimate and compare FHH incomes. It argues that the central measurement challenge is the distinction between the farm business and the FHH. Farm business income is often observable, but household economic welfare depends on total income, income composition, household structure, wealth, liquidity and exposure to volatility. The evidence does not support a simple conclusion that FHHs are universally income‐disadvantaged. In many developed‐country contexts, average income differences narrow or disappear once household size and composition, in‐kind benefits and the choice of comparison group are taken into account. However, income variability, low‐income incidence, distributional outcomes and asset‐rich but cash‐constrained households remain important policy concerns. The review highlights the limits of farm accountancy data for evaluating income‐support objectives and argues for stronger household‐level and linked administrative data systems. Improved measurement is essential for credible policy targeting, transparent evaluation and analysis of FHH well‐being, resilience, generational renewal and social sustainability.
